CHURN-POWER.

To all whom it may concern:

Be it known that I, JESSE E. HULLEN, a citizen of the United States,residing at Brownsville, in the county of Haywood and State ofTennessee, have invented certain new and useful Improvements in Churn-Powers, of which the following is a specification.

This invention relates to power machinery for operating churns orsimilar devices, and has particular reference to the specific noveldetails of construct-ion hereinafter fully described and claimed, andillustrated in the accompanying drawings, in which- Figure 1 is a sideelevation of the invention, certain parts being broken away to disclosecertain structural features; Fig. 2 is a transverse vertical section,substantially on the broken line 2 2 of Fig. 1', Fig. 3 is a transversesection on the line 3 3 of Fig. 1, and Fig. 4 is a vertical transversesectional detail substantially on the broken line 4 4 of Fig. 1.

Throughoutthe following detail description and on the several figures ofthe drawings similar parts are referred to by like reference characters.

The invention comprises a power shaft mounted transversely in bearingsin a suitable rigid frame-work 11. The shaft 10 is adapted to beoperated at one end 10 by any suitable mechanism preparatory to theoperation of the machine in the manner hereinafter described. The frame11 includes a pair of parallel vertical standards 12 at each sidethereof and extending substantially throughout the entire height of themachine. The frame includes also another pair of vertical parallelstandards 13, extending downwardly -from the top of the frame for ashorter distance than the standards 12 eX- tend, and are braced at theirlower ends by across piece 14 connected to the inner members of thepairs of members 12. The shaft 10 is journaled in all of said pairs ofstandards. A power cable 15 is connected to each end of the shaft 10between the adjacent pair of standards 12, and to the other end of thecable is connected a weight 16 having flanges 16 embracing saidstandards 12, whereby the weight is properly guided in its verticalmovements. Power being applied to rotate the shaft 10 the cables 15 arewound thereupon and the weights 16 hoisted toward the top of the frame.A hub 17 is connected rigidly to the shaft and adjacent Specification ofLetters Patent.

Serial No. 518,577.

thereto is a gear wheel 18, normally loose upon the shaft. A pin 19movable radially in the hub 17 may engage the ratchet teeth 1S of thewheel, whereby the hub will drive the wheel in one direction, but permitindependent movement in winding. A finger piece 19a of the pin 19projects laterally through a bayonet slot 19b and whereby the pin may bedrawn inwardly toward the shaft 10 against the tension of a spring 19C,and when the pin is rotated slightly by the finger piece so as to bringsaid finger piece into contact with the shoulder at the end of the slot,the pin may be held withdrawn out of engagement with the ratchet teeth18 leaving the power shaft 10 and hub 17 free to rotate in eitherdirection without disturbing the gear wheel 18. A crank shaft 20, havinga crank 21, is journaled in the short standards 13 and one of the sidestandards just below and parallel to the power shaft 10. A pinion 22 ismounted loosely on the crank shaft and is in mesh with the gear wheel18. Another gear 23, likewise loose on the shaft 20, is rigidlyconnected to the pinion 22. The gear 23 meshes in turn with a secondpinion 24, which together with a companion gear 25, is journaled looselyupon a counter-shaft 26. The last mentioned gear 25 meshes with a pinion27 rigidly secured to the crank shaft, whereby when the power shaft 10and the intermediate gearing are operated the crank shaft will be drivenat a correspondingly high speed. The crank shaft may be provided with afly-wheel 28 if desired. A pitman 29 is connected to the crank 21 at oneend and is pivoted at its other end at 29 to a cross head 30 havingflanges 30 and slidable vertically between the intermediate standards13. The transverse form of the cross head is similar to that of theaforesaid weights 16, with reference to its guide flanges. Vhen thecrank shaft is rotated the pitman and cross head will be reciprocated,and the churn dasher 31, connected detachably to the cross head by meansof a pin 32, will be given a vertical reciprocation in a well knownmanner.

1n oider to separate the churn 33 from the machine it is only necessaryto remove the pin 32, allowing the dasher 31 to drop downwardly into thedotted line position indicated in Fig. 1, at which time the upper endthereof will be free from the brace 14 in which it normally has bearing.

In order to control the speed at which the machine will operate underthe infiuence of the weights 16 there is provided a governing deviceincluding a frame 34, vertically disposed and having pairs of laterallyextending ears 35 having horizontal slots 35. Said ears lie in proximityto the opposing faces of one of the side standards l2 and one of thecentral standards 13. By virtue of said slots the frame 34 may beadjusted bodily laterally and is adapted to be secured in such adjustedposition by means of set bolts 36 passed through said slots and intosaid standards. The adjacent end of the crank shaft 20 is provided witha pinion 37 which meshes with a gear 38 secured to a shaft 39 journaledin the last mentioned standards. The shaft 39 has connected thereto aworm gear 40 meshing with a worm 4l, the ends of which are supported byadjustable screws 42 mounted in the frame 34. The proper contact betweenthe worm and worm gear will be maintained by the aforesaid adjustment ofthe frame 34. A friction brake member 43 is mounted stationarily on theframe 34 and coperating therewith is a brake member 44 loosely mountedupon the shaft of the worm 4l and slidable vertically thereon. Themember 44 is provided at its upper end with a sleeve and flange 45against which a pair of bell cranks 46 have bearing at one end. Saidbell cranks are pivoted to a yoke 47 which rotates with the worm-shaft.If the speed at which the machine operates becomes too great, a pair ofballs 48 connected to the other ends of the bell cranks 4G will causethe depression of the rotary brake member 44, bringing the same intofrictional contact with the sta tionary member 43.

Having thus described the invention, what is claimed as new is:

l. In a device of the character set forth, the combination of a framecomprising pairs of vertical parallel standards, a power shaft journaledtransversely in said standards, a crank shaft journaled in certain ofsaid standards below the power shaft, weights connected to said powershaft and guided for vertical movement by two pairs of said standards, apower pinion rigidly connected to one end of said crank shaft, a hubrigidly connected to said power shaft, a gear wheel mounted on saidpower shaft adjacent to said hub and having a series of ratchet teethsurrounding the hub, a pin carried by said hub and movable radially toengage said teeth to lock said gear to said hub, gearing between saidgear wheel and said power pinion, and means connected to the oppositeend of said crank shaft for controlling the speed of said crank shaft,substantially as set forth.

2. In a device of the character set forth, the combination of a framehaving pairs of vertical standards, a` power shaft journaled in saidstandards, weights connected to the ends of said shaft and guided forvertical movement between certain pairs of said standards, a crank shaftjonrnaled below and parallel to the power shaft, means for driving thecrank shaft from the power shaft, and means to control the speed ofrotation of the crank shaft, said means including a vertical framemounted between certain of said vertical. standards and adjustablelaterally thereof, a worm shaft ourneled in said adjustable frame,friction members associated with said worm shaft, and means between theadjacent end of the crank shaft and said worm shaft whereby the latteris driven from the crank shaft.

In testimony whereof I affix my signature in presence of two witnesses.
